“Could not install Gradle distribution” is a Gradle Wrapper failure message, not a diagnosis. The nested exception and the distribution URL tell you whether to investigate a timeout, a Java certificate trust problem, an incorrect Wrapper setting, or a local cache or permissions issue. Start with those details; installing a separate Gradle version usually will not fix a Wrapper download failure.
1. Find the actual cause in the complete error
Copy the full message, including the distribution URL and the innermost exception. The headline alone is too broad to identify a fix. For example, SocketTimeoutException points toward a failed or slow network connection, while SSLHandshakeException or PKIX path building failed points toward Java failing to trust a certificate chain.
Other nested errors can indicate that the Wrapper cannot write to its configured cache location. Match the fix to the underlying exception rather than changing network settings for every case.
2. Check the project’s Wrapper URL and version
Open gradle/wrapper/gradle-wrapper.properties in the project and inspect distributionUrl. The Wrapper uses this URL to obtain the Gradle version configured for that build, then provisions and reuses the distribution under GRADLE_USER_HOME. See Gradle’s Gradle Wrapper documentation for the configuration and URL format.

#1 Best Overall
- Confirm that the URL names the intended Gradle version and distribution.
- Do not change the version just to make a download succeed; first check whether the project and its plugins support the proposed version.
- For most builds, Gradle’s
-bindistribution is smaller than-all; the latter also includes sources and documentation.
Installing another Gradle version on the computer does not normally change the version the project Wrapper downloads. The Wrapper’s configured URL is what matters for this build.
3. Reproduce the failure with the project Wrapper
Run the project’s Wrapper from a terminal to see whether the failure also occurs outside the IDE. From the project directory, use the command for your operating system:
Rank #2
- macOS or Linux:
./gradlew build - Windows:
gradlew.bat build
If the terminal run fails, use its full exception to continue diagnosis. If it succeeds while IDE sync fails, compare the IDE’s Gradle and Java configuration with the environment used by the terminal. Gradle recommends the Wrapper for running a build with the project’s controlled Gradle version; a Gradle forum discussion also suggests command-line reproduction as a way to distinguish an IDE issue from a download problem (Gradle 8.2 timeout discussion).
4. If the cause is a timeout, check the network path
A timeout means the Wrapper did not complete communication with the distribution host or a destination reached during the download. Check the network path before retrying:

- Check whether a VPN, firewall, or organization network policy blocks the connection.
- If the network requires a proxy, verify its host, port, and authentication details with your administrator.
Gradle documents JVM proxy properties in gradle.properties. For HTTPS, the relevant properties include systemProp.https.proxyHost and systemProp.https.proxyPort; proxy credentials and nonProxyHosts may also be needed. Use values for your network, not the documentation’s example host. See Gradle networking configuration.
In one forum report, disconnecting a VPN resolved a timeout, but that is an environment-specific example, not a general fix. A separate discussion describes timeout and proxy conditions on a corporate network; it likewise does not establish a universal cause (Gradle corporate-proxy discussion).
5. If the cause is SSL or PKIX, investigate Java’s trust chain
An SSL handshake or PKIX path-building error means Java could not validate the certificate chain it received. If your organization inspects HTTPS traffic through a proxy, the proxy may present a certificate chain that the Java runtime used by the Wrapper does not trust. Confirm the organization-approved certificate authority and trust configuration with your administrator, and check which Java runtime the Wrapper is using.
Do not disable TLS certificate validation or import an arbitrary certificate to bypass the error. A historical Gradle forum report discusses a corporate-proxy scenario, but it is an anecdote rather than current guidance about Gradle’s distribution servers (Gradle corporate-proxy discussion).

If the nested error mentions access denied, a missing path, or another local I/O problem, inspect GRADLE_USER_HOME and confirm that the configured directory exists and is writable. The Wrapper stores and reuses its downloaded distribution there.
If the error indicates an incomplete or corrupted download, address the underlying cause first, then inspect the corresponding Wrapper cache entry and retry. Avoid deleting unrelated Gradle data: removing it will not fix an inaccessible directory or a blocked connection.
7. Use retries and checksums for the problems they address
The Wrapper supports download retry and backoff settings that can help when a connection is unstable. Gradle also supports the distributionSha256Sum property in gradle-wrapper.properties to verify a distribution; a checksum mismatch fails the build. See the Wrapper documentation for the available settings.
Retries can help with transient interruptions, and a checksum can detect a distribution that does not match the expected value. Neither fixes an incorrect URL, a blocked route, an untrusted certificate chain, or a cache directory the Wrapper cannot access.
